And you don't think that Jon Harrop could write a book about Haskell
if he honestly came to think that it were a superior all-aroung
language? The fact that he *didn't* mindlessly reject F# in favor of
O'Caml when F# came out (despite the fact that at the time his company
was deeply (exclusively?) invested in O'Caml and arguably had a vested
interest in having F# fail to gain support) suggests that he is able
to fairly evaluate the merits of other languages. Doubtless he has
biases, but there is no reason to think that they are any greater than
the bias of any programmer who has invested substantial amounts of
time in becoming fluent in a particular language.

But an advocate isn't a judge. Nobody is handing down binding
decisions here - they are just advocating their positions. It would be
better to compare JH to a defense lawyer. You can't reject the
defense's arguments just because the lawyer has a vested interest in
the outcome of the trial.
